Genzyme’s LEMTRADA™ Application for MS Accepted for Review by the FDA

Genzyme, a Sanofi Company announced that the U.S. Food and Drug Administration (FDA) has accepted for review the company’s supplemental Biologics License Application (sBLA) file seeking approval of LEMTRADA (alemtuzumab) for the treatment of relapsing multiple sclerosis (RMS). The company also reported key highlights from the U.S. launch of once-daily, oral AUBAGIO (teriflunomide).

LEMTRADA sBLA Accepted by FDA

The FDA has accepted for standard review the company’s sBLA file seeking approval of LEMTRADA. Genzyme expects FDA action on the application in the second half of 2013. Genzyme has already submitted its marketing authorization application for LEMTRADA to the European Medicines Agency (EMA) and the review process is underway. The Committee for Medicinal Products for Human Use (CHMP) opinion for LEMTRADA is expected in Q2 2013.

The LEMTRADA clinical development program includes CARE-MS I and CARE-MS II (Comparison of Alemtuzumab and Rebif® Efficacy in Multiple Sclerosis), randomized Phase III studies comparing LEMTRADA to a standard of care MS treatment, Rebif, in patients with relapsing-remitting MS who were naïve to prior treatment or who had relapsed while on prior therapy, respectively. Genzyme announced publication of results of these studies in The Lancet in November 2012.

AUBAGIO Early Launch Indicators in the U.S.

Since its launch in October, once-daily, oral AUBAGIO has shown very encouraging early launch indicators among U.S. prescribers.1 Key highlights from the launch include:

• More than 80 percent of MS specialists in the U.S. have prescribed AUBAGIO; • Approximately 1 in 5 patients prescribed AUBAGIO were treatment-naïve; • More than 50 percent of AUBAGIO patients were most recently on Copaxone® or Avonex®

“Genzyme is making a difference for people living with MS and realizing its vision of being leaders in MS,” said Genzyme President and CEO, David Meeker, M.D. “The initial uptake of AUBAGIO by U.S. prescribers shows the importance of a once-daily oral option in MS. In addition, the acceptance of the LEMTRADA file in the U.S. marks another important milestone in bringing this potentially transformative therapy to MS patients. We look forward to a series of product launches in 2013 in Europe and other major markets.”

Fluctuations in female sex hormones could play a role in the development of allergies and asthma, a major review of evidence suggests. Analysis of studies involving more than 500,000 women highlights a link between asthma symptoms and key life changes such as puberty and menopause. Further investigation could help explain why asthma is more common in boys than girls in childhood, but more common in teenage girls and women following puberty.
